IMPROVED SASH-FASTENING.

Specification forming part of Letters Patent No. 44,730, dated October 18, 1864.

y in which- Figure 1 is a side sectional view of my invention applied to a window-sash wx. Fig. 2 indicates the line of section; Fig. 2, a horizontal section ofthe same, taken in the line y y, Fig. l.

Similar letters of reference indicate like parts.

This invention relates to a new and ini. proved fastening for window-sashes, which serves both as a fastening and lock.

The object of the invention is to obtain a fastening for the purpose specified, which 1n a y be cheaply manufactured, readily applied to the window, and not liable to get out of re pair.

A represents a window frame, and B the sa ih. These parts, possessing no novelty in their construction, do not require a minute de icription.

O represents a metallic case, which is fitted in one of the stiles c of the window-frame A, and has a horizontal slot, b, made in each side of it to receive journals c c, which are at each side of a latch or catch, D, at the outer end ot' the saine. This latch or catch is simply a tlat plate, beveled or rounded at its'outer end,

as shown at d, and provided with a handle or lever EX, which extends outward by the side of the sash.

In the outer end of the latch or catch D there is made longitudinally a hole, c, to receive a spiral spring', E, the outer end of which bears against the back of the case C, and in the upper part of said case there is placed a spiral spring, F, which bears upon the latch or catchD, as shown clearly in Fig. 1.

The spiral spring E has a tendency to press the latch or catch D out from the case (l, while the spring F has a tendency to press said latch or catch down upon the bottom of the case.

In the edge of the sash B, which adjoin-s the stile c ofthe window-frame, there is made a notch, G, which may be lined with metal, in order to resist abrasion and wear. This notch G is made at such a point in the sash that it will when the sash is down receive the outer end of the latch or catch, the spring E pressing` the latter into said notch, the forming a lock.

In order to release the sash, the latch or catch is forced into the case C and nearly out from the notch G by actuating the lever or handle EX, and the sash may then be raised, the latter forcing upward the outer end of the latch or catch to an inclined position, as shown in red in Fig. 1, the inner end of the latch or catch bearing against the back of case O and holding the sash at any desired point within the scope of its movement.

In order to release the sash, so that it may 4be lowered, the lever or handle EX is pressed upward, which takes the pressure of the latch or catch D oft' from the edge of the sash, and the latter descends, the springs E F pressing the outer end of the latch or catch D into notch G as the sash reaches a closed state.

The latch or catch D, in combination with v the springs E F and notch G, all arranged within the case O and applied to the windowframe and sash, to operate in the manner substantially as and for the purpose set forth.
